Extreme Networks Data Sheet
Enhanced Wireless
Performance
Altitude 450/451 APs provide up to 300
Mbps which is about a six-fold throughput increase over existing 802.11a/b/g
wireless LAN APs. For wireless 802.11n
clients, this tremendous increase in
wireless performance is comparable to
100Mb Fast Ethernet wired LAN
throughput, the current standard for
many enterprises.
Dual Concurrent Radios with 3x3
MIMO Capability
Altitude 450/451 APs contain dual,
concurrent independently-managed
radios, one operating in the 2.4 Ghz
band for 802.11b/g/n service and the
other operating in the 5 GHz band for
802.11a/n service. Each radio has a set
of three transmitters/receivers which
enable 3x3 MIMO functionality. With the
multiple signal streams, along with
Orthogonal Frequency-Division
Multiplexing (OFDM) modulation, the
AP provides higher bandwidth, greater
range, and better overall performance
compared to 2x2 MIMO, 2x3 MIMO, or
legacy 802.11 a/b/g APs.
In addition to MIMO technology, the
802.11n AP and client can bond two
adjacent 20 MHz channels to create a
single 40 MHz wide channel. This
potentially doubles the throughput from
a standard 20 MHz channel, used in
legacy wireless networks.
Optimal Use of Existing Network
Infrastructure
The increased performance of 11n AP
can strain the wired infrastructure and
even require that the wired network be
upgraded to handle the increased
wireless traffic. To avoid such an
expensive upgrade, Extreme Networks
offers an innovative distributed wireless
architecture. Unlike other wireless
solutions, Summit WM distributed
architecture offers the choice to tunnel
user traffic to the controller in the core
or be locally bridged at the AP across
the edge switch. This traffic distribution
can be configured on a per SSID basis.
This local bridging approach allows high
bandwidth data and video traffic to be
bridged locally resulting in distributed
traffic management. With local bridging,
there is no need to send all traffic back
to the core and then turn it around and
“hairpin” it back to the Edge.

Reliable Coverage
In addition to enhanced performance, the
11n technology enables faster, cleaner and
more reliable signals. With fewer dropped
packets and fewer retries, network
reliability is greatly enhanced. Improved
range and coverage increases user
productivity, simplifies network design and
operations, and ultimately reduces service
calls to the IT helpdesk.
Increased User Productivity
The increased bandwidth of Altitude 450/451 APs enables wireless
users to access to high bandwidth
applications like multimedia, rich e-learning, video conferencing, collaborative
design and so on. Additionally, with 11n it
is easy to set up temporary classrooms and
facilities without pulling new cables. The
end result is better productivity for mobile
users and less IT time spent on wired
infrastructure setup and teardown.
Superior Return on Investment
Extreme Networks’ Altitude 450/451 APs
offer a superior return on investment
when considering the total costs of upfront
capital expenditure, network upgrades,
installation, and operation. The AP’s
unique conformance to the 802.3af Power
over Ethernet (PoE) standard and the
innovative distributed architecture of
Summit WM controllers drive these
financial advantages.
Efficient Power Consumption
Altitude 450/451 APs provide full functionality, including 3x3 MIMO dual concurrent
radio operation, while being powered by
industry-standard 802.3af PoE. This
unique capability reduces the overall cost
of implementing an 11n wireless LAN
compared to alternative 11n enterprisegrade APs that require one or more of the
following upgrades to avoid degraded
operation:
1. New higher-power non-standard PoE
switches
2. Allocate two standard PoE ports per
AP and double the cable run to each
AP
3. Restricting PoE cable runs to much
less than standard 100m. This limits
deployment flexibility for optimum
wireless coverage and capacity
4. AC drops near the AP for powering
external power adapters for APs
All of these options can significantly
increase capital and operational expenses.
The lower power consumption of Altitude 450/451 APs compared to
competing APs enables “greener” operation. By consuming at least four watts less
per AP than a competitive 11n AP, the
total power consumption across several
APs can be significant. For example, with a
250 11n AP installation, Extreme Networks
wireless solution would save the customer
about 1KW of power!
Minimized Network Upgrades
Extreme Networks distributed wireless
architecture enables enterprises to
transition to 11n technology without costly
upgrades to the wireless or wired infrastructure. Summit WM controllers are 11n
ready thereby avoiding costly fork lift
upgrades. Additionally, with local bridging
capability organizations can fully utilize
the existing edge network infrastructure
for high-bandwidth 11n traffic, rather than
tunneling all of the user traffic back to the
controller across the wired core. An 11n
AP, at peak performance can handle up to
250 Mbps (TCP payload) of user traffic
across both radios operating simultaneously. Tunneling all of the user traffic from all
the APs connected to a controller can
severely strain the wired infrastructure as
well the WLAN controller in the core
network. Distributing the user traffic
across several edge switches optimizes the
operation of the wired network.
Based on application, some user traffic
would need to be tunneled to the controller. This would include voice traffic that
requires session mobility. Guest traffic
should be tunneled back to the controller
for security reasons. Typically high
bandwidth employee data traffic can be
locally bridged at the edge of the wired
network.
Faster, Easier Installation
In addition to the previously mentioned
PoE power advantage, Altitude 450/451
APs have a number of features that enable
quick deployment. The APs can be
mounted on the wall, on drop ceilings, or
out of sight in the ceiling plenum space.
The power-efficient AP design also
minimizes vents in the housing, making
the APs particularly resistant to tampering
and dust. Altitude 451 operates with
external antennas that provide extended
coverage and minimal interference in hard
to reach areas. If necessary, approved
Altitude 450 and Altitude 451 Access Points­—Page 2
Extreme Networks Data Sheet
third-party antennas can be used to
provide shaped or directional wireless
coverage.
Altitude 450/451 AP also supports
Extreme Network Summit WM plug-andplay installation. When connected to the
network, the AP automatically and
securely registers with the Summit WM
controller. The plug-and-play installation
of a centrally managed network eliminates manual configuration of each AP
individually. This is ideal for remote sites
where IT staff may be limited or
non-existent. Altitude 450/451 has a
self-sensing 10/100/1000 Ethernet port
for 100+ Mbps transfer rates. The port
can fall back to 100 Mbps if it is connected to a 10/100 Ethernet port of an edge
switch.
For existing wireless LAN installations,
Altitude 450/451 APs can seamlessly
operate in conjunction with existing
Altitude 350 APs in the same wireless
network. This enables legacy and 11n
clients be serviced by legacy APs and
the 11n APs operating in mixed mode.
Additionally, Altitude 450/451 APs use
the same mounting brackets as Altitude 350, allowing easy upgrades as organizations transition to 11n AP
deployment.
Central Configuration and
Monitoring
All Altitude 450/451 APs are centrally
managed by the Summit WM controller
using graphical management interface.
APs can be configured, enabled,
disabled, and managed separately or in
groups. Different APs can beacon
different SSIDs, allowing guest access,
for example, to be available in conference rooms only but not in the corporate
office area. The management interface
also presents and reports on alarms,
traps, statistics and events across the
wireless network managed by the
controller.
delivers higher performance, more
scalability and high availability.
Enterprise-Grade Voice
Performance
Altitude 450/451 APs enable low latency
support for the industry leading VoWLAN
devices. The APs support over-the-air QoS
protocols such as SpectraLink Voice
Priority (SVP) and 802.11e based WMM
specifications. Priorities can be set
according to SSID, allowing critical
real-time voice traffic to be assigned to a
distinct high-priority queue. Interoperability
with wired network traffic prioritization
ensures end-to-end QoS as the traffic
traverses the network.
Comprehensive Security
Altitude 450/451 AP can support several
security profiles based on application.
On-board hardware accelerated encryption
engine supports WEP, TKIP and AES
standards. The AP can participate in
several client/user authentication schemes
including 802.1X or PSK authentication.
Enterprises can utilize their existing AAA
infrastructure to deliver comprehensive
link security and configure different
encryption options ranging from no
encryption for guests, shared key for
phones and PDAs, to WEP, WPA, and
WPA2. Unique security profiles are
configured on a per SSID basis. The
Altitude 450/451 AP is transparent to
end-to-end VPN tunnels like IPSec, PPTP,
L2TP.
Enterprise Grade Wireless
Services
Extreme Networks wireless solutions
optimize performance and availability to
provide robust Enterprise-grade wireless
services. All 802.11 time-critical
functions, such as hardware-accelerated
encryption, over-the-air standards based
(WMM) QoS and RF management is
implemented in Altitude 450/451. This
